700c, 27-Inch & 650c

The Roval SLX 24 Disc is a no nonsense wheelset. At only around 1515 grams, it's designed for light overall weight, but this doesn't mean that it sacrifices anything to strength or durability. Instead, its 20mm-wide alloy rims work to bolster the aforementioned characteristics, while also providing the optimal tire profile in order to enhance both confidence and feel on the road. Meanwhile, the rims have been built to Roval aero hubs that feature fast-engaging DT 350 star-ratchet internals at the rear. Add it all up, and you get a wheelset that checks all of the boxes for daily training and CX racing—lightweight, stiff, and incredibly reliable.

Making up about 50% of your total race time, the bike portion of a triathlon is where equipment choices can make the difference between first and fifth, and no other equipment choice will save you more time than a disc wheel. While traditionally-shaped disc wheels are faster than their spoked counterparts, the Roval 321 Disc for disc brakes turns conventional design on its head, creating the fastest wheel on the planet.
Disc wheels often fall into two categories—a completely flat shape, with structure coming from carbon fiber and a honeycomb-foam filling, or a spoked wheel that's been faired with a carbon fiber cover. In our quest to break traditions, the 321 uses a single layer of 1k carbon fiber on each side of the wheel, and it all comes together at the brake track bridge. This kind of carbon fiber is rarely used in bicycle components due to its high manufacturing cost, but it offers a bevy of performance benefits. This coveted carbon is much lighter than other layups, like 3k and 12k, and it can only be laid by the most skilled of carbon fiber craftsmen. It's complicated, but the payout is worth it, as it delivers a supple ride and one of the lightest disc wheels available. And in the real world, this means that it'll spin-up quickly and reduce fatigue over the length of the course.
Stiffness is often the “hot-topic” in the disc wheel world, but we think it’s an interesting conversation. It's long been thought that efficient power transfer and high stiffness are directly correlated, but through extensive field-testing, we've determined that this isn't the case at all. In fact, our initial disc was so stiff that, under power, it wouldn't flex with the frame and this caused brake rub. This wrongly creates the perception of a flexy wheel, when really, the wheel is actually too stiff. In order to solve the brake rub problem, we first designed our optimal aero shape and then worked on our internal stiffness targets to fit within what we consider to be a desirable frame stiffness.
And while light overall weight was a development priority, our focus was aerodynamics. Through hours of Computational Fluid Dynamics (CFD) and testing in the Win Tunnel, we developed a never-before-seen shape that's optimized to work with a tire for on-bike airflow. What this translates to is an all-carbon disc wheel that, on the non-drive-side, has a shape that's as aerodynamic as our current understanding allows, and a drive-side shape that's as aerodynamic as the wheel-dish and derailleur clearance will allow for.
To save every possible watt, we've also added CeramicSpeed bearings and DT Swiss 240 hub internals into our hub. Each 321 Disc wheel is also 2Bliss Ready right out of the box and comes with a padded wheel bag, quick-release, and tubeless valve stem.
Designed for the most uncompromising athletes in the world, with engineering to match, the 321 Disc is the world's most advanced disc wheel for your race against the clock.

Engineered for light weight without sacrificing durability, the Roval SLX 24 is a no nonsense wheelset. The 20mm wide, tubeless ready, alloy rims provide an optimal tire profile to enhance confidence and feel on the road. Roval aero hubs with DT 350 star-rachet internals round out the package to create a light, stiff, and reliable wheelset. Tipping the scales at only 1460 grams, this wheelset is equally at home in a hilly road race or logging big miles training in the off-season.

The pinnacle of aluminum road wheels. The ceramic OXiC surface coating brings brake performance to rim brakes as it has never been seen before. The rims are wide, asymmetric, and lightweight, making for an outstanding stiffness-to-weight ratio. If set up tubeless, supreme comfort and grip are added to the athletic character. And, at just 1450g, this wheelset is both extremely practical and competitive, very much in tune with its stealthy appearance.

The PR 1400 DICUT 21 OXiC may just be the pinnacle of aluminum road wheels. The ceramic OXiC surface coating brings unheard-of braking performance to a rim brake system. The rims are wide, asymmetric, and lightweight, making for an outstanding stiffness-to-weight ratio. If set up tubeless, supreme comfort and grip are added to the mix, and, at just 1450g, this wheelset is both extremely practical and competitive.
